Use hdparm to check whatever you got dma enabled for your disks. From
the low performance I guess it's not...
And to comment some other responses:
Scsi DO have some benefits over ide, but for a normal user/workstation
it's certainly not worth the extra cost in my opinion. For life
supporting systems, maybe...
To hook up 7 ide devices, just buy 3ware's ATA raid card with 8
channels. The total cost including disk will be a lot lower than for
scsi.
And when you need a few tens of TB you want a standalone raid system
anyway...
When it comes to quality, I doubt there's any real differens these
days. And even if there is; disks will eventually fail, that why you
use raid-X (X!=0).
As for performance, the "normal" pci bus itself will limit you to
133MB/s or similar...
